我有一个名为“book”的自定义帖子类型和一个名为“books”的自定义CPT分类法。这种分类法的一个术语是“接受你自己”。以下是“接受你自己”归档页面的代码（URL:my\\u site/books/accepting yourself/）：

if ( have_posts() ) : 
    while ( have_posts() ) : the_post(); 
    echo get_the_title();
    endwhile;
endif;

这将返回自定义分类法“books”中的所有“book”帖子，即8篇帖子。相反，它只返回一个。

以防万一，下面是定义自定义帖子类型和custon分类法的代码：
